TENS Units
TENS stands for Transcutaneous Electrical Nerve Stimulation. TENS Units are typically used for acute and/or chronic nerve related pain conditions. TENS machines send stimulating pulses across the surface of the skin and along the nerve strands.
The stimulating pulses help prevent pain signals from reaching the brain. TENS devices also help stimulate your body to produce higher levels of endorphins; our bodies own natural painkillers.
